Will Ferrell is returning to studio 8H this weekend to host Saturday Night Live. Ferrell is no stranger to the show, still reigning as one of its most prolific cast members of all time. What that also means is that he has a trove of characters from the show that he made famous. Leslie Jones is obviously a fan as she decides to do a mean Will Ferrell and imitate some of his most memorable, and its obvious that Leslie needs more cowbell.
